I need help with identifying this Mercedes driver seat.
 

I recently received a black Mercedes driver seat. It's all leather, but thats all I know besides the controls for the seat on the bottom. I'll supply some pictures and hopefully someone knows what it is and how much they are worth. This seat was nodded to make into a desk chair, but it weighs over 80 pounds easily. Now I just want to sell it to get what ever out of it. Thanks for the help guys. :D
